WELL Certification is based on performance and requires a passing score in each of the seven categories of the WELL Building Standard. WELL Certification is awarded at one of three levels: Silver, Gold and Platinum. WELL Certification is achieved when projects demonstrate all Preconditions. Higher certification levels above Silver can be achieved by pursuing Optimization Features. Because health and wellness objectives vary from one building to the next, WELL provides flexibility when selecting Features that best suit the project owner’s goals.
